There she worked on developing a nuclear fusion reactor, but grew disenchanted with the long-term prospects of fusion.

FORBES: 30 Under 30: Energy

In addition, many of our laboratories studying nuclear fusion are closing, while France plans to open a nuclear-fusion reactor in 2019.

The Earth is warmed naturally by its own nuclear fission reactors within and also by the sun, that big nuclear fusion reactor.

He first attracted attention for creating a nuclear fusion reactor at 14.

Indeed it would not, strictly speaking, be a fusion reactor at all.

ECONOMIST: How to get an energy rush without doughnuts

We thus need to pursue fusion to the reactor scale through constructing Iter to see whether and to what extent it can contribute.

BBC: VIEWPOINT

With the blended reactor, the neutrons from fusion reactions would wedge themselves into the nuclei of this waste, making them unstable enough to split and produce heat.

FORBES: A Nuclear Hybrid

In addition to clearing our last remaining scientific hurdle, we need to advance a parallel engineering agenda into key reactor technologies that will enable commercial fusion power plants to reliably deliver electricity in a highly competitive market.

CNN: Nuclear fusion is the 'perfect energy source'

The good news is that the big names in nuclear energy -- like Areva, Hitachi, General Electric and Toshiba -- have recently been joined by a bevy of high-tech start-ups seeking to develop advanced nuclear-reactor designs for both fission and fusion energy production.
